Terminal blocks are modular, insulated blocks that secure two or more wires together. Terminal blocks consist of an insulating body and a clamping device. Their flexibility allows wiring to be centralized and makes it easier to maintain complex control circuits

Connection heads, also referred to as thermoheads or thermocouple heads, provide a means for connecting temperature sensors and extension wires.

Phototransistors are solid-state light detectors with internal gain that are used to provide analog or digital signals. They detect visible, ultraviolet and near-infrared light from a variety of sources and are more sensitive than photodiodes. This category includes photodarlingtons. 

Predictive maintenance (PdM) and condition monitoring systems are used to predict equipment maintenance, and to monitor corrosion, oil condition, bearing wear, overheating and other parameters than can lead to the breakdown of capital equipment.

Diacs are bi-directional diodes that switch AC voltages and trigger silicon controlled rectifiers (SCRs) and triacs. Except for a small leakage current, diacs do not conduct until the breakover voltage is reached.

Programmable logic controllers (PLCs) are the control hubs for a wide variety of automated systems and processes. They use a wide variety of inputs and outputs and provide network capability.

Material handling automation services provide single source automated equipment and systems solutions for the material handling process.

Temperature instruments use contact or noncontact methods to measure temperature. Products include dial, digital, industrial and laboratory thermometers; temperature probes, indicators, and sensors; RTD elements and transmitters; and thermistors, thermocouples, thermopiles, and thermal switches. 

RF repeaters have independent paths for reception and transmission, through which they collect and send signals to antennas and other stations.

Electronics standoffs and electronics ferrules are small components for spacing or positioning electronic devices on printed circuit boards.

PCB terminal blocks are modular, insulated devices that mount on printed circuit boards (PCBs) and secure two or more wires together. Some have integral pin terminals and mount through holes in the board. Others plug into PCB-mounted pin strips

Human machine interfaces (HMI) are operator interface terminals with which users interact in order to control other devices

Remote terminal units (RTUs) connect directly to sensors, meters, dataloggers or process plants, and collect and transmit data automatically

Patch panels are groups of ports used to connect lines between communications and electronic devices. Connections are made manually with small patch cords, and are easier to wire than automatic switches. Wireless patch panels are also available.

Solderless terminals are passive conductors used to facilitate a connection that is not soldered
